Cannot connect to PC

Hello,

please can you explain what exactly you would do and what you try?

In the project a S7-300 and HMI RT is configured.

The ip settings are different, the HMI Works in 192.168.x and the PLC in 192.168.1.x.

So there can no communication works between this devices.

You have no HMI Connection configured between the HMI Station and the PLC, should this device communicate each other or not?

Nex is, have you runing a HMI RT to which you would Downlod?
If not then is better to use the RT Button or the Simulate Button .

Regards

Christoph
